Several years ago, someone referenced a lesser-known collection of full screen vintage diesel photos, probably on Flickr. I can't find the link either here or on my computer. Anyone recall who it might be?

Thanks, Mitch. Neither seems to be the one in question, but both these gentlemen have some worthy shots to look over.
Maybe I can find it by starting with my forum join date (unless it was in that massive thread that admin deleted)

Todd definitely has some choice stuff posted. I "followed" his collection some time ago.

The ones I'm looking for were pretty much uncropped and uncorrected. Maybe I bookmarked the location (among a zillion other places!).

If I come across anything like that as I expand my horizons in Flickr, I'll let you know. In the meantime, you may want to check out Mel Patrick, whose stuff is sublime. Also, Hal Reiser, a contemporary of mine who has a lot of nice northeast, especially D&H, material.
